In math processor variables are related to image index (iM#123}. Names are not accepted.
How to get the index from a named image?
By breaking the double quotes and using $image_name
, which will be substituted in the argument of, e.g., fill
before execution:
foo :
sp lena,eagle
f. "i(#"$lena",x,y) = i"
Ja, super, I never thought to use image names as variables
repeat {iM#$label}
with an image named label works. Thank you!
You don’t even need the braces anymore:
repeat iM#$label
is OK too.
Interesting. What if there was a variable with the same name as the image? Would the next assignment replace the original?
